Impact of Adverse Network Conditions on P2P-TV Systems: Experimental Evidence
In this paper, the authors define an experimental set-up to analyze the behavior of commercial P2PTV applications under adverse network conditions. Their goal is to reveal the ability of different P2P-TV applications to adapt to evolving network conditions, such as delay, loss, available capacity, and presence of background traffic and to check whether such systems implement some form of congestion control. They apply their methodology to four popular commercial P2P-TV applications: PPLive, SOPCast, TVAnts and TVUPlayer. Their results show that all the considered applications are in general capable to cope with packet losses and to react to congestion arising in the network core.
